Conversion of an EA MT4 to MT5

Hello,

I just want to convert an EA MT4 to MT5

Currently the EA is in MT4 version, it is in good standing with the requirements of the MQL5 site to be put on sale.

The version will also have to respect these requirements.

I specify that the EA works on 28 pairs on a single chart.

The EA must be able to be backstable on MT5 with all pairs at the same time.

I do not need the MT5 version, I do it mainly to be able to make backtest of all pairs at the same time
This is my main requirement.

This EA can not make Backtest in MT4 either, even with a single pair because it uses The Currency Strenght.
He makes a calculation USD, EUR, GBP .... and all the pairs at the same time in order to get the strength of each currency.

The deadline is very important for me, I could not wait a month for example ....

If you need it to make your price proposal, I can provide a video or sees the code.
This allows you to see the number of lines and evaluate if it is a difficult or not work.

I'm waiting for your proposals
